摘要
罗式胜在“关于普赖斯曲线方程中参数的讨论”一文中提出了估计普赖斯曲线方程中参数的两个方法,但具体计算中存在缺乏量化标准的缺陷。利用概率统计中的2 σ准则给出一个确定参数的改进方法,引入去除异常数据的量化标准,即使其更具有合理性和可操作性。
Two estimation methods for parameters in Price's curve equation were proposed by Luo Shisheng in the paper 'Discussion on the parameter in Price's Curve Equation'. A modified parameter estimation method with a rule of two sigma is given. The modified parameter estimation, in which a quantitative criteria for removing the irregular data has been introduced, is more reasonable and operative than methods proposed by Luo Shisheng in paper.
